The new season, once again hosted by Julie Chen, will feature two new twists: For the first time ever, three houseguests will be nominated for eviction each week instead of two. Also (and perhaps more importantly), viewers will vote weekly for the "Big Brother MVP," who will receive special powers in the game. Both twists will be explained in greater detail on the show's premiere Wednesday (8/7c, CBS).

As usual, the contestants will live in a camera-rigged house where they backstab, yell at and sleep with fellow competitors until one lucky player walks away with $500,000.
